Reference Data
1. Solderability
(1) Test Method
(2) Test Samples
Subject the chip capacitor to the following conditions.
Then apply flux (an ethanol solution of 25% rosin) to the
chip and dip it in 230D eutectic solder for 2 seconds.
Conditions:
GRM21 : Products for flow/reflow soldering.
(3) Acceptance Criteria
With a 60-power optical microscope, measure the surface
area of the outer electrode that is covered with solder.
(4) Results
Expose prepared at room temperature (for 6 months and
12 months, respectively)
Refer to Table 1.
Prepared at high temperature (for 100 hours at 85D)
Prepared left at high humidity (for 100 hours under
90%RH to 95%RH at 40D)

2. Board Bending Strength for Solder Fillet Height
(1) Test Method
Solder the chip capacitor to the test PCB with the amount
of solder paste necessary to achieve the fillet heights.
Then bend the PCB using the method illustrated and
measure capacitance.
